Thanks for reminding me that this is coming up Noiesmo.
From the Wikipedia Entry for Software Freedom Day
Software Freedom Day (SFD) is an annual worldwide celebration of Free/Libre and Open Source Software (FLOSS). SFD is a public education effort, not only to celebrate the virtues of Free and Open Source Software, but also to encourage its use, to the benefit of the public.
SFD was established in 2004 and was first observed on August 28, 2004 when over 70 teams participated. Since that time it has grown in popularity as more than 300 teams from over 60 countries celebrated on the second SFD, held on September 10, 2005. The primary sponsor for 2005-2006 is Canonical Ltd, the company behind the Ubuntu, a Linux distribution.
Software Freedom Day is now the third Saturday of each September. For 2006, SFD will be September 16th.
I’m not sure what we’re doing yet, its roughly 5 weeks away. Here’s some ideas. I hope my friends and the people I’ve met through FOSS and free culture would like to spend the day celebrating with us.
